Application filed July 30,1912. Serial No. 712,268.

To all whom it may concern:

Be it known that LhLours BULASKYyEM citizen of theUnited States,zresiding in the borough of Brooklyn of itheicityof New York, in the county ofNew York, in :the

State of New York, :have invented certain new and useful Improvements in 1I-Iat-Trimming Machines, of which theifollowing; is a specification, reference being had to the accompanying drawings, which form: a 1 part hereof. j

This invention relates particularly to machines for trimming the edges of felt hats and in which the felt is fed by two cooperate ing presserwheels, the cutting bein efi'ected simultaneously by a circular. knife, which rotates with the upper presser wheel and cooperates with the lowerapresser wvh'eeh In machines of this character; .asqheretofore used, both presser wheels are mounted upon relatively fixed shafts, and one feed wheel,

usually the upper, has a. central aperture larger than theshaft ;or:gear ghub upon which it is mounted. so that it imayyield slightly to accommodate varying thicknesses of felt, the feed wheelbeing ClI'lVBIli only by frictional contact with the :face of the gear or of a disk affixed to the gear. Thefriction driving of the feed wheel, which. was a.

necessary result of EtlliS construction, leads to irregularities in thefeed and one object of the presentinvention is to improve the construction so that, while the presser wheel may yield vertically to accommodate .vary ing thickensses of felt, it shall yet be driven positively so that it cannot have driving slip;- at the same time provision is made? for regulating. the friction. between the feed wheel and its driver; so that. it may yield upwardly moreor less easily as the conditions of the work may require;

Another object of the invention is to provide means for lifting the upper feedwheel clear of the lower feed wheel for the .pur-

pose of clearing the work from; the feed wheel.

Still another; object of the. invention is to provide means for regulating the. downward pressure of the upper :feed wheels Still another object is to provide means for efl'ecting a relative displacement of the two feed wheels horizontally for the purpose of enabling the work to be removed and inserted readily.

The. invention will be more fully exaccompanyinggdrawings in which 3 it is ill-ustrated and in which- Figure 11 is a view in frontelevation, partly broken out, of a felt trimmer which embodies the several. features of the invention. Fig.1 2 is atop View of the same.

The machine shown in:the drawings com.-.

prises a frame a having a lower arm a and 1 an upper arm a all suitably shaped to sup= port the workingparts. The frame is providedwith a stud a uponwhichis mounted a grooveddriving pulley b. A pinionlb' on the hub of the driving :pulley meshes with. a gear. wheel ib on a shaft I) mounted in suitable bearings in the frame, while a gear wheel I)? meshes .Wltll a corresponding gear wheelc fixed on a shafti a which is mounted in suitable bearings inthe lower arm of the frame and carries the lower feed Wheel Provision is made whereby the lower feed wheel 0 maybe displaced horizontally with respect to the upper feed wheel. Acollar a is fixed on the shaft. 0' and its hub .0 is threaded to receive a sleeve 0 against the end of which rests awasher 0. Aspringc bearing at one end against the bearingga rests at its other end against the washer and so tends to hold' the shaft "and the feed wheel. c? inv their normal. position. The sleeve 07' is adjustable on the hub 0 so as to permit the tension'of the spring to be ad- ,justed. Loosely mounted on, the shaft 0 and between the collar'c 'and the vertical arm a of the frame, is a collar which carries a cam 0 provided with a handle 0 The cam 0 bears against an abutment a? on the'frame and is provided with a dwell, When the handle b is in the position shown in Figsl and 5 the" [feed wheel 0 is {permitted to occupy its noras indicated at 0 maloperative position, but when the handle is turned up to or toward'the horizontal position the shaft 0 and the lower feed wheel 7 '0 are moved to the left to throw the lower feed wheel out'of line with the upper feed wheel, as shown by dottedlines inFig. 1.

' The shaft 6 is provided as usualwitha pinion Z9 indicated 'by dotted lines in Fig,

3, which meshes with an idler 6 While the latter in turn meshes with a pinion b, allas shown in Fig, 7;

indicated by dotted lines in Fig; ,3 and as The idler b may be mounted upon a'stud b andthe pinion b upon a longerstud b bothsecured in the head a of the frame. The pinion: b is formed with or secured to the hollow shaft or sleeved and, is recessed as at d" to receive an independent, loose ,bearing ring d Screws d inserted from the opposite face of against theadjacent'member,whioh is the -drivingdisk d. s The latter is slotted,=as at 'd, to engage a stud d on the sleeve (Z, so that the driving disk'j shall be driven posipositively from, the driving disk wol the pinion b suppor -t the bearing ring 6Z2 so that it may be crowded more or less tively with the pinion b but may be moved relative theretoby the ring d and screws 03*. i The 'upperdrivin-g wheel 6. has a'central aperture 6 sufliciently large vto permit cons'iderablelmovement j of the driving {wheel with respect to the sleeve d andit has also, on its face adjacent to the driving disk 0?, pins 0 which enter enlarged recesses d in the adjacent face of the driving disk, so that .the feed wheel may have considerable ver:

tical: movement with, respect to the axis of the sleeved, but shall nevertheless be driven washer f, having [a flanged. hub f, is received on the sleeved againstthe right hand face of the feed wheel e, the hub f being,

erate with said cam.;

the washer f on theone side and the driving disk d on the other side may be regulate by crowding the rin 6Z2 againstthe driving disk (F by means 0% the screws (i against which the ring (Z rests.

Theupperfecd wheel e is lifted, to clear,

thelower'feed wheel, by a lifter h which partly encircles the feed wheel at its front 1 edge; At its rear edge the feed wheel bears against a fixed guide h to prevent the/feed wheel from being crowded to the rear when the lifter actsJ jJThe lifter may be operated by any convenient means, but preferably is arranged to be operated by the same controller handle by which theh'orizontal dis lace-- ment of'the lower feed wheel [0 is e ected.

..For thisypurpose' the, stem it? of th'e'ilifter,

mounted in guides 7L3 and pulledtnormallyi down by a spring'ht, is connected at itsuP- per end with a leverh which ispivotedrat it on the upper frame a? ofthe'frame and is connected at its other end by a link it? with the hub '0 of the cam 0 so that when -the cam is rotated to displace the lower feed wheel horizontally, the upper'feed' wheel is at the same time lifted; vertically. Inorder that the lifting movement of the upperfeed wheel may take place after the lateralmove" ment of the lower feed wheel has been ac.- oomplished, lost motion is provided for,- preferably by a-slcttedlink h to which] the link h is connected, w{hileit is itself loosely held to the top of the 'cam by a'screw h",

link enters the hub of the cam.

In order that the upper feed wheel may whichjpasses through the slot 'of-the short i '100 be c pressed downward with an adjustable but yielding pressure there is provided an 'ad I" justable spring presser is which comprisesa plunger is having in. its extremity a roller 70 to bear against the periphery of the upper feed wheel and guided in a cylinderk r A spring is, placed within the-cylinder,bears-1:

against theplunger Z2 and its tension.may

be adjusted by a follower if and adjusting,

screw is which is threadedin the cap of the Y cylinder.

It will be understood that various changes 'may be made in thedet-ails of the Parts to suit different conditions of use and; isnot limited to the precise construction shown,
